Several binary systems have been detected at High Energy (HE, E > 100 MeV) and/or Very High Energy (VHE,E > 100GeV) gamma rays. Some of them are X-ray binaries in which accretion feeds relativistic radio jets and powers the non-thermal emission (i.e. microquasars), whereas in others the power comes from the wind of a young pulsar instead of accretion. Although the power mechanism in these systems is different (accretion vs. pulsar wind), all of them are radio, X-ray and gamma-ray emitters, and have a high-mass bright companion (O or B) star that is a source of seed photons for IC scattering and target nuclei for hadronic interactions. I review here some of the main observational results on the non-thermal emission from X-ray binaries as well as some of the proposed scenarios to explain the production of gamma rays.
